9．Americans use many expressions with the word"dog"．People in the US love their dogs and treat them well．They take their dogs for walks，let them play outside and give them good food and medical care．However，dogs without owners lead a different kind of life．The expression"to lead a dog's life"describes a person who has an unhappy life．
Some people say we live in a dog-eat-dog world．That means many people are competing for the same thing，like good jobs．They say that to be successful，they have to work like a dog．This means they have to work very hard．Such hardwork can make people dog-tired．And，the situation would be even worse if they became sick as a dog．
Some people say，"Every dog has its day．"This means that every person enjoys a successful period during his or her life．To be successful，people often have to learn new skills．Yet，some people say that you can never teach an old dog new tricks．They believe that old people don't like to learn new things and will not change the way they do things．
Some other people are compared to dogs in bad ways．People who are unkind or uncaring can be described as meaner than a junkyard dog．Junkyard dogs live in places where people throw away things they don't want．But mean dogs are often used to guard the property，for they bark at or attack people who try to enter the property．However，sometimes a person who appears to be mean and threatening is really not so bad．We say his bark is worse than his bite．
Dog expressions are also used to describe the weather．The dog days of summer are the hottest days of the year．A rainstorm may cool the weather but we don't want it to rain too hard．We don't want it to rain cats and dogs．
64．A person who lives an unhappy life can be described as"C"．
A．becoming sick as a dog             B．living in a dog-eat-dog world
C．leading a dog's life               D．working like a dog
65．The underlined word"mean"in Paragraph 4 most probably meansB
A．selfish           B．violent       C．wild           D．poor
66．What can we learn from the text？
A．Everyone can be successful if he learns from the old．C
B．It might be difficult for the young to learn new skills．
C．Fierce persons aren't so awful as they appear sometimes．
D．Junkyard dogs are careful in money arrangement．
67．To support his idea，the author develops the text mainly byD．
A．listing reasons                      B．using idioms
C．making comparisons                   D．giving examples．

分析本文通过举例说明美国人使用了很多与"狗"相关的习惯．

解答 64．C 细节理解题．根据第一段中的"The expression"to lead a dog's life"describes a person who has an unhappy life．"可知正确答案．
65．B 词义猜测题．根据第四段中的"But mean dogs are often used to guard the property，for they bark at or attack people who try to enter the property．"可知，用来看护财产的狗应该是"凶猛的"．这样，当有人接近它守护的财产时，它就会冲他狂吠或袭击．
66．C 推理判断题．根据第四段中的"However，sometimes a person who appears to be mean and threatening is really not so bad．"可知表面凶猛的人并不一定真的很坏．
67．D 篇章结构题．通读全文，作者在介绍与"狗"相关的习语时，列举了很多例子，这些例子大多与人有关，也与天气有关．

10．Most students do an IQ test early in their school career．Even if they never see their results，they feel that their IQ is （81）what determines how well they are going to do in life．When they see other students doing （82）better （good）than them，they usually believe that those students have （83）a higher IQ and that there is nothing they can do （84）to change （change） facts．However，new research into EQ suggests that success is not （85）simply （simple） the result of a high IQ．
While your IQ tells you how （86）intelligent （intelligence） you are，your EQ tells you how well you use your intelligence．Professor Salovery，who （87）invented （invent） the term EQ，gives the following description：At work，it is IQ （88）that gets you promoted．Supported by his academic research，Professor Salovery suggests that when （89）predicting （predict） someone's future success，their character，（90）whichis measured by EQ tests，might actually matter more than their IQ．

20．

A wagging （摇） tail is a form of dog communication．Dogs wag their tails to tell us something about how they're feeling．
There are probably few people who haven't seen a dog wagging his tail，and most of the time it's obvious what the dog is trying to tell you with this kind of body language．It is important，however，that you pay attention to how the dog is holding his tail when he's wagging it．
Is it relaxed and moving back in forth？Is his body moving along with the wagging？Or is the tail high and moving quickly back and forth while the dog's body remains fairly erect and stiff （竖直僵硬的）？Where the tail is and the way a dog holds his body while he's wagging it can give you a clue about what he is trying to communicate．
Most people look at a dog with a wagging tail and assume he is happy．Most of the time this is true，but there are times when a dog wags his tail right before he becomes aggressive．If a dog is wagging his tail and the rest of his body seems relaxed or is moving along with the wagging，you are dealing with a happy and comfortable dog．
If a dog is holding his body erect and stiff while wagging his tail，however，he may be telling you that he's feeling territorial or uncomfortable with something that is going on around him．In this case，the dog's tail will be held high and moving back and forth rapidly．This discomfort can be a sign to attack．
This is one reason people sometimes report that a dog was wagging his tail right before he bit someone．So if you come across a dog you don't know who is wagging his tail，check out what the rest of his body language is telling you before you approach．

32．In what situation do we know a dog is happy？C．
A．When we have a close look at him．
B．When we try to communicate with him．
C．The dog wags his tail and his body remains relaxed．
D．The dog moves his body along and holds his tail high．
33．A dog's tail holding high and moving back and forth rapidly shows he may beA．
A．aggressive B．frightened C．friendly D．relaxed
34．What are people expected to do when meeting a strange dog？B．
A．Train him to be friendly．B．Judge him by his body language．
C．Ask the owner for help．D．Approach him slowly．
35．What is the best title of this passage？D．
A．Signs of a Dog's Bites．
B．A Special Communication．
C．A Pet Dog-Human's Friend．
D．Dog Feeling Expression-Wagging Tail．

17．A credit card that won't work unless its owner's voice is heard may become an important weapon in the fight against economic fraud（欺诈）．
The card using a built-in voice-recognition chip requires users to give a spoken password that it recognizes．The idea is to prevent thieves from using a stolen card to buy goods online．
A model built by engineers in California packs a microphone，a loudspeaker，a battery and a voice-recognition chip into a standard-sized credit card．The card is the length and width of an ordinary credit card but about three times as thick．The company now plans to make it thinner．
The voice card is based on an earlier Beep card technology designed to prevent fraud in online deals．The Beep card has no microphone，but has a built-in loudspeaker to utter an audible （听得见的） ID signal by a computer's microphone to an online server（服务器）．By confirming that signal matches the information in the card，the server can make sure that the user is not simply keying in a credit card number but actually has the card in his hand．The ID code，which only the server knows，changes each time the card is used．
This prevents fraudsters recording the beeps，noting the card details and then playing back the audible ID when they key in the details later．But this earlier Beep card technology cannot prevent illegal use of stolen cards．The new voice card can．The new voice card doesn't identify itself by its ID until it has confirmed the real user's spoken password．Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy．The challenge for Beep card has been to develop voice-recognition and audio circuitry（声音电路）．
The voice-recognition credit is powered by a mini battery．To extend batter life，the electronics have only to be switched on when the card is being used．Pressing a button on the card's surface allows one to hear a female voice saying，"Say your password．"If the voice-recognition software proves that the password is real，it sends its ID，which the server then identifies，allowing the deal to continue．

59．Why is the voice credit an important innovation？D
A．It is cheap to make and buy．B．It can leave voice messages．
C．It makes online shopping easy．D．It makes fraud more difficult．
60．What is the problem with the model card？B
A．It is too large．B．It is too thick．
C．It can't be used online．D．It has no loudspeaker．
61．Which of the following about the earlier card is TRUE？D
A．Its owner can change the ID code at will．
B．Its user needn't key in the credit card number．
C．It can record its user's spoken password．
D．It can be used by someone who has stolen it．
62．What can we infer from the last paragraph？A
A．Further improvement should be made to extend battery life．
B．Only female voice passwords can be recognized by the card．
C．There are no limits to the use of the card．
D．Female customers will like using it．

4．If you thought it was cold where you are at the moment，then a visit to the Russian  village of Oymyakon might just change your mind．
    With the average temperature for January standing at-50C，it is no wonder the  village is the coldest inhabited settlement in the world．Known as the'Pole of Cold'，the coldest temperature recorded in Oymyakon was-71.2C，which is the lowest  recorded temperature for any inhabited location on earth．
    Ironically，Oymyakon actually means'non-freezing water  due to a nearby hot  spring．Most homes-in Oymyakon still burn coal and wood for heat and enjoy few  modern conveniences．
    Nothing grows there so people eat reindeer （驯鹿） meat and horse meat．A single shop provides the town's bare necessities and the locals work as reindeer-breeders，
hunters and ice-fisherman．
    The village is located around 750metres above sea level and the length of a day  varies from 3hours in December t0 21hours in the summer．And despite its terrible  winters，in June，July and August temperatures over 30c are not uncommon．
    There are few modern conveniences in the village-with many buildings still   having outdoor toilets and most people still burn coal and wood for heat．When coal  deliveries are irregular，the power station starts burning wood．If the power ceases，the town shuts down in about five hours，and the pipes freeze and crack．
    Daily problems that come with living in Oymyakon include pen ink freezing，glasses freezing to people's faces and batteries losing power．Locals are said to leave  their cars running all day for fear of not being able to restart them．
    Even if there was coverage for mobile phone reception，the phones themselves  would not work in such cold conditions．
    Another problem caused by the frozen temperatures is burying dead bodies，which  can take anything up to three days．

14．Birds can learn to choose the best building materials for their nests，according to scientists．
It was previously thought that birds'choice of nest materials was determined by their genes，that is，each type of bird has their own methods of building nests born with them．But an experiment has now shown this to be a more complex activity．This study，published in the Royal Society Journal Proceeding B，involved giving zebra finches （斑胸草雀） a choice of soft and hard string to build the their nests．"We found that they liked the harder string，"explained the lead researcher Dr Bailey from the University of St Andrews．"It's more efficient for them to build with-they can build a nest with fewer materials．"
Dr Bailey and her colleagues were planning to test the learning ability of birds； their test aimed to work out if the birds could learn to tell the difference among the materials based on their quality．To test this，they gave one group of finches flexible，soft string to build with，and another group harder string．Both groups of birds were then offered a choice between the soft and hard string．And the birds that had been made to build their nests with the soft string immediately chose the more rigid building materials．
"There is a great diversity of nests in the natural world，"said Dr Bailey．"And because birds are not considered to be as clever as people，who can learn to use different materials quite easily，the assumption had been that there was a genetic pattern in the birds'brains．"
"This shows that actually learning is also very important for their decisions．"Mike Toms from the British Trust for Ornithology said the research made a lot of sense．
"It may help to explain the variety of materials that may be used by individuals of the same species nesting in the same general area．"He told BBC news．

55．What is the purpose of the experiment mentioned in the text？D
A．To make sure finches can use different building materials like people．
B．To find which finch is more skillful in choosing building materials．
C．To test the ability of finches to learn from other birds．
D．To confirm finches'ability to identify building materials by learning．
56．Which is the RIGHT order of the steps in the experiment？A
a．Building materials were offered to the finches．
b．The finches were divided into two groups．
c．The researchers chose some finches．
d．The finches made a choice of the building materials．
A．c，b，a，d
B．c，d，b，a
C．a，c，b，d
D．b，a，d，b
57．What can we learn from the last paragraph？B
A．Birds of the same species choose to build nests in the same area．
B．It's common that the same species birds use different materials．
C．Birds sometimes can not find various building materials．
D．People should help birds build nests if possible．
58．In which column of a newspaper could we find this text？C
A．Garden．
B．Environment．
C．Science．
D．Architecture．

18．New research offers fresh insight on when to launch a product or service，and shows that being first to market isn't always a competitive advantage．

19．Charter schools operate with public money but without many of the rules that govern traditional public schools．In the United States the rules for charter schools differ from state to state．But in general these schools have greater freedom to decide what to teach and how to teach it．
         A charter school might be independent or connected to the local public school system．It might be started by teachers，parents or，in some cases，a profit-making business．It sets up the goals of the school and other details like how student performance will be measured．And now a group of charter schools have formed the Green Charter Schools Network （GCSN）．The idea is to have environmentally friendly school buildings but also to go further than that．
         The schools teach students to be concerned with community issues （社区事务） that affect them and the environment．For example，young children grow crops in a school garden and learn about healthy eating．Older students help recycle waste from the cafeteria．And local schools share what they grow in community gardens with people in need．
         Jim McGrath is president of the GCSN．He says there are about two hundred"green"charter schools across the United States．The plan is to also include traditional public schools as well as private schools．"The most important thing is that every one of us-every child，every adult-has a responsibility that our action，every action we make has an effect on the earth that we live in．And that our natural resources are never unlimited．And that if we want a positive earth for future generations，we all need to make commitments to be change agents so that we don't destroy our natural resources，"said Jim McGrath．
         The GCSN holds its first national conference this October in Minnesota．Supporters of green schools say their goal is to expand the movement across the country．
66．Which of the following is tine of a charter school？D
A．It has more strict school rules．
B．It is built for disabled students．
C．It is financed by profit-making business．
D．It generally has greater freedom of teaching．
67．The GCSN：willD．
A．destroy our natural resources
B．combine private schools together
C．build more schools throughout the world
D．do more to make a difference to the environment
68．Students in the GCSN mayC
A．join in political issues
B．recycle waste from factories
C．grow crops in a school garden
D．share what they grow with one another
69．Jim McGrathC
A．holds several national conferences
B．takes charge of all charter schools in the US
C．suggests everyone should be responsible for the earth
D．believes our natural resources are never running out
70．The passage is mainly aboutC．
